Bacterial pneumonia

Bacterial pneumonia is an acute lower respiratory tract infection characterized by bacterial invasion and subsequent inflammation of the pulmonary parenchyma and alveolar spaces It affects pediatric, adult, and geriatric populations across both community-acquired and hospital-acquired settings, with higher morbidity and mortality occurring in older adults, young children, and immunocompromised individuals Clinically, this process manifests with systemic and localized features, including fever, r...

It affects pediatric, adult, and geriatric populations across both community-acquired and hospital-acquired settings, with higher morbidity and mortality occurring in older adults, young children, and immunocompromised individuals Pathophysiologically, the host immune response to bacterial pathogens—most frequently organisms such as *Streptococcus pneumoniae*—triggers cytokine release, increased capillary permeability, and an influx of neutrophils, resulting in alveolar exudate accumulation and ...

Pathophysiologically, the host immune response to bacterial pathogens—most frequently organisms such as *Streptococcus pneumoniae*—triggers cytokine release, increased capillary permeability, and an influx of neutrophils, resulting in alveolar exudate accumulation and consolidation

Pathophysiologically, the host immune response to bacterial pathogens—most frequently organisms such as *Streptococcus pneumoniae*—triggers cytokine release, increased capillary permeability, and an influx of neutrophils, resulting in alveolar exudate accumulation and consolidation

Clinically, this process manifests with systemic and localized features, including fever, rigors, dyspnea, pleuritic chest pain, hypoxemia, and a productive cough with purulent sputum
